Rose Rosemann is a minor antagonist in Marvel's Spider-Man. She runs an auction house called Rosemann's, which was used to cover up Wilson Fisk's schemes.
Mary Jane appeared at the auction house to report on a story, which Rose initially refused to let her because she was supposed to come tomorrow, but managed to convince her. She gets suspicious of Mary when she starts asking questions on whether Rose knows about Wilson's fraud schemes, and asks her to leave. She is later taken hostage by the Inner Demons.
History[]
At some point, Rose met and befriended Kingpin, which asked her to run an auction house for her. She agreed. When Wilson was arrested, she was forced to put the items on auction. Mary Jane came in the day before she was supposed to and tried to report on a story. Rose first refused, but changed her mind when she thought she was changing plans.
She gave MJ a tour, showing her Japanese items and art. When she started asking questions about whether Rose knew about Wilson's money laundering schemes, she started to get suspicious. She then ordered her to leave, before reluctantly letting Mary use the bathroom.
She then called Mary's supposed boss Craig, who told her that Mary wasn't even one of his reporters. During the time, Mary had found a file in a statue containing Oscorp's experiments on "Devil's Breath". Rose was later held hostage by Inner Demons looking for the file, before she was saved by Spider-man.
